How the Tools Work

All PaperPixels tools run entirely in your browser using JavaScript. Conversions are calculated locally on your device — nothing is sent to any server. The pixel conversion tool accepts any DPI value you enter, making it useful whether you're designing for screen (72 or 96 DPI), standard print (150 or 300 DPI), or high-resolution professional output (600+ DPI).

Who Uses PaperPixels

PaperPixels is used by graphic designers setting up document templates, photographers preparing prints for specific frame sizes, web developers creating print-ready page layouts, students working on reports or posters, printers and print service customers verifying file dimensions before submitting jobs, and office workers who simply need to know the difference between A4 and Letter before printing a document received from another country.

Accuracy

All paper size dimensions are sourced from the ISO 216 standard for international sizes and from ANSI/ASME Y14.1 for North American engineering sizes. Photo and poster dimensions follow industry conventions used by major print labs. Pixel calculations use the exact formula: pixels = (dimension in inches) × DPI, with millimeter inputs first converted using the exact 25.4 mm/inch conversion factor.
